The Imogene Pass Run (IPR) is a 17.1 mile point-to-point mountain race within the western San Juan mountains of Colorado. The course runs along a route which connects the towns of Ouray (7810 ft.) and Telluride (8750 ft.) by way of 13,114 foot Imogene Pass. The IPR is held on the first Saturday after the Labor Day holiday, at the seasonal transition from late Summer to early Fall.
